Chapter 17: Writing Database Components

Overview

In Chapter 9, "Writing Delphi Components," we explored the development of Delphi components in depth. Now that I've discussed database programming, we can get back to the earlier topic and focus on the development of database-related components.

There are basically two families of such components: data-aware controls you can use to present the data of a field or an entire record to the users of a program; and dataset components you can define to provide data to existing data-aware controls, reading the data from a database or any other data source. In this chapter, I'll cover both topics.
